require is not defined using rollup

I have the following rollup.config.js:

import commonjs from 'rollup-plugin-commonjs';
import nodeResolve from 'rollup-plugin-node-resolve';

export default {
  input: 'input.js',
  output: {
    file: 'output.js',
    format: 'iife'
  },
  plugins: [
    nodeResolve(
      {
        jsnext: true,
        main: true
      }
    ),
    commonjs({ include: 'hello.js' })
  ]
}

I have the following input.js which requires hello.js:

var hello = require('./hello.js');

console.log(hello);

and hello.js is simply:

module.exports = 'hello';

I would like output.js to not include the require syntax and for it to be replaced it with the string 'hello'.

I instead still see the line var hello = require('./hello.js');

How can I replace this line with a rollup plugin? (I thought that is what the commonjs plugin was for).

Thanks in advance for the help!

Worked it out.

The problem was with my input.js file.

The plugin doesn't support require, but the plugin facilitates module.exports.

Changing input.js to be:

import x from './hello.js';

console.log(x);

worked.
